In principle, nothing ever has to reside in a separately compiled library.

You don't see my point because you think of the header-only approach
as a good thing, whereas in my mind headers should be limited to
things that must be in a header, such as functions for which inlining
is critical, as well as template definitions. This reduces physical
coupling, which is only a problem in large scale projects;
unfortunately by the time it becomes a problem it is already too late.

By the way, Boost is way past that point, so a good argument against
my position is that one more header-only lib isn't going to make
things (much) worse. :)
